A new height in client service

Architect: Skidmore, Owings & Merrill

In 2009, MTH built the spectacular “Ledge” tourist attraction onto the sky deck at long-time client Willis (formerly Sears) Tower, and when a problem occurred recently our crews were airborne to fix the minor damage with practically no downtime. On a Wednesday night, visitors were frightened to observe what they thought were cracks in the glass floor of the observation

perch. The attraction was shut down, but by Thursday afternoon, the cracked surfaces, actually thin protective coatings atop the 10,000 lb-rated glass floors, had been replaced with customary MTH speed and efficiency.

Unfailing attention to national
treasures of every size

Standing barely four feet above the surface of the earth, Mies Van Der Rohe’s Farnsworth House near Plano, Illinois, attracts a towering number of visitors itself—tens of thousands a year.

The house is owned by the National Trust for Historic Preservation, which has entrusted MTH Building Maintenance Services to keep its glass and metal in pristine condition.
